You, an intellectual: 9+7=16
Me, with ADHD: if you take 1 from 9 and give it to 7 thats 8+8 and 8×2 is 16
Someone, usually a Teacher: NOT LIKE THAT YOU HEATHEN
This is literally how I would have done it
that’s how i do it in my head, honestly
either that or 9+7 is equal to 10+6 which is 16
but that IS how I’ve been taught in primary school?
I would have been inclined to think 10+7=17 and 17-1=16 because it is easier for me to think in 10s. We actively encourage this kind of differentiation and flexibility in my school.
